If you undo the cat-to-midpipe joint, take out the bolt that holds the cat up to a bracket at rear of motor, then you can get that exhaust pipe out of the way and over to the side and really get at things, then reinstall it.
That bolt at rear runs into a made nut on a bracket off front of cat. I hit the nut for about two minutes with a MAPP gas torch till it is glowing hot, then come down from above from rear of engine with a LONG extension on a ratchet, 13mm socket, starting about dead beside oil filler cap as I recall, you can see the head of the bolt, get right onto it, and crack it loose.
Pipe and cat might tug a little heavy on the wiring to the front oxy sensor so have some blocking around to support it.
Loosen serp belt and remove the AC compressor and set it up over towards RH fender, keeping lines attached. Bungee it up there if you want. To get AC pump off I always hacksaw away a small projection at top middle of the aluminum pump bracket, lets it come out the top. No conceivable need for that projection that I can see. Then remove bracket for AC pump from the block. That gives you lots of access.
Grind the original nut down or hacksaw thru it down to near the stud threads and it should unscrew. Then use an acorn-type nut, oiled so it will come off, to reinstall the stud in the turbo. Loctite if you want. Hold stud still, even clamping a narrow needlenose vise grip right onto its threads up close to the turbo, when removing the acorn nut. Even if jaws mar the threads a little it will be in an area where a nut never runs.
Then get an appropriate new nut. I have found that on high miles cars those nuts burn down and are way under stock size anyways. If that's so on the two good ones, replace them too.
